Sigla: Gesture Shortcuts

Sigla puts every shortcut you use one flick from wherever you already are.

Draw a C and Chrome opens. Draw an M and it is Maps. Or skip the drawing and
tap: a deck of buttons fans out from under your thumb, on top of whatever app
you are in.

DRAW A MARK
Sigla knows 43 marks out of the box — all 26 letters, the digits 0 to 9, and
seven shapes: square, triangle, diamond, tick, arrow, star and heart. Pair two
letters for the apps that need them, so FB is one gesture rather than two.
It matches on the shape you drew, not on how straight you were holding the
phone: marks are recognised up to 20 degrees off-axis. Past that, C and U stop
being distinguishable, so it stops rather than guesses wrong.
What gets saved is your stroke, exactly as you drew it. The tidying up happens
inside the matcher and never touches what you see.

A DECK, NOT A LIST
Buttons fan out in a ring around wherever you touched. A solver places them so
none lands under your own thumb or off the edge of the screen, and it never puts
more than nine around one anchor — past that the outer ones stop being reachable
one-handed. When you need more, the unlock adds groups: a button that opens a
ring of its own.

WHAT A MARK CAN DO
- Open an app
- Open a link or a deep link
- Torch, ringer profile, volume, camera, Wi-Fi, Bluetooth, settings
- Brightness and rotation lock
- Start a timer of any length, set an alarm, show alarms
- Search, open, map, dial or share whatever is on the clipboard
- Run a Tasker task
- Back, Home, Recents, screenshot, lock screen, notifications, quick settings

REACH IT FROM ANYWHERE
A floating button, which hides itself in the apps you tell it to. A Quick
Settings tile. A 1x1 home screen button and a resizable widget. And an entry in
the text-selection menu, so a highlighted address can go straight to a map.

NO ACCOUNT, NO CLOUD, NO ADS
No sign-up, no login, no sync — there is no server to sync with. Your gestures,
your deck and your settings are stored on this phone and nowhere else. There is
no ad SDK and no analytics in this app, so there is nothing collected and nothing
to share.

ABOUT PERMISSIONS
Most of Sigla works with nothing granted at all.
The floating button needs permission to draw over other apps, and runs a
foreground service while it is switched on so the system does not kill it. Turn
the button off and that service stops.
The accessibility service is optional. It exists only for Back, Home, Recents,
screenshot, lock screen, notifications, quick settings and the power dialog,
which have no other API — and it is declared so that it cannot read the contents
of your screen. Every other action works without it.
Brightness and rotation lock ask for their own permission the first time you use
one, not on the way in.
Sigla does not use QUERY_ALL_PACKAGES to find your apps.

FREE, WITH AN OPTIONAL ONE-TIME UNLOCK
Free gives you 5 gestures and 5 deck buttons, which is enough to replace the
shortcuts you actually reach for. One payment raises that to 20 gestures and 40
buttons, and adds groups — a button that opens a ring of its own — and a
different deck in the apps you choose. A single purchase, not a subscription.

MAKE IT LOOK LIKE YOURS
Four button sizes, three button shapes, six colours, three ink weights, and a
resting opacity so the button fades back when you have not touched it. Choose how
the deck opens — pop, sweep or instant — and how fast.
